I was in Shanghai recently, where Twitter is blocked, and yet there were ads and billboards across town with hashtags on them.

The beauty of Twitter is that more and more people are flocking to it because it's shrinking their world.

When youre doing what you love to do, you become resilient. You create a habit of taking chances on yourself. If you do whats expected of you, and things go poorly, you will look to external sources for what to do next, because that will be your habit. You will be standing there frozen. If you are just filling a role, you will be blindsided.

The Internet destroyed most of the barriers to publication. The cost of being a publisher dropped to almost zero with two interesting immediate results: anybody can publish, and more importantly, you can publish whatever you want.

Believe that if you make courageous choices, and bet on yourself, then you will have an impact.

What is the thing that matters most to making progress right now?

Managing by trying to be liked is the path to ruin.
